BUS – unlike other European countries, there is no rail system anywhere in Iceland, not even the capital city, Reykjavik. Thus, locals rely entirely on bus transportation – both to get around within Reykjavik, as well as to connect to other parts of the country.
Reykjavik’s local bus system is called Straetó (www.straeto.is). A single ride costs ISK 350 (€2.15) (which includes a free transfer). Here are the other fares:
9 ticket card = ISK 3000
1 day card = ISK 900
3 day card = ISK 2,200
